TECHNICAL FIELD

The present invention relates to an information provision method for use in an information providing system configured to collect log information from one or more electrical devices of one or more users via a first network, and to transmit the log information to a computer of one or more service providers via a second network.

BACKGROUND ART

In recent years, there is an expectation that devices such as home appliances or AV equipment in a home are connected to a cloud server via a cloud network, log information including operation histories of the devices is collected in the cloud server from the devices such as home appliances or AV equipment, and services are provided with use of the collected log information. For instance, there is proposed a system in which a datacenter operating company operating a cloud server cooperates with a service provider providing services, and the service provider utilizes log information collected by the cloud server, whereby personal services matching with the lifestyle of the user are provided, and marketing analysis is carried out using statistical information.

Further, for instance, Patent Literature 1 discloses the information disclosing server 201 configured such that when public information requested from the client 202 includes attachment information, confirmation information indicating that the public information attached with the attachment information is provided is transmitted to the client 202, and when a reply indicating acceptance is obtained from the client 202, the public information attached with the attachment information relating to e.g. copyright is provided.

The aforementioned system, however, is under consideration. Further improvement is necessary to put the system into practice. For instance, log information to be collected includes personal information relating to the privacy of the user. In particular, personal information cannot be provided to a third party without permission of the user. User's permission is individually necessary in order to provide personal information.

DESCRIPTION OF EMBODIMENTS

The following matters are taken into consideration when the aforementioned conventional system is put into practice.

For instance, when the number of devices owned by the user and connectable to a network increases, it may be difficult for the user to discriminate between registration and non-registration as to whether log information is provided with respect to each of the devices. In this case, it may be difficult or impossible to appropriately manage the setting as to whether providing log information with respect to each of the devices. As a result, the user may inadvertently provide log information of a device of which providing information is not intended to a service provider.

Further, for instance, when the number of devices owned by the user and connectable to a network increases, it may be difficult for the user to discriminate between registration and non-registration as to to which one of the service providers, log information is to be provided with respect to each of the devices. In this case, for instance, it may be difficult or impossible to appropriately manage whether providing log information to a predetermined service provider is permitted. As a result, the user may inadvertently provide log information to a service provider to which providing log information is not intended.

In view of the above, the inventors have achieved the invention according to the following aspects on the basis of the aforementioned findings.

An information provision method according to an aspect of the invention is an information provision method for use in an information providing system configured to collect log information from one or more electrical devices of one or more users via a first network, and to transmit the log information to a computer of one or more service providers via a second network. The information provision method includes accumulating, in a first database, a first identifier identifying each of the one or more service providers, and first device information indicating an electrical device to be designated by each of the one or more service providers in association with each other; accumulating, in a second database, a second identifier identifying each of the one or more users, and second device information indicating an electrical device to be used by the one or more users in association with each other; extracting the service provider associated with the first device information when the second device information is updated by addition of a new electrical device to be used by one of the one or more users, and when the new electrical device is included in the electrical devices indicated by the first device information; and providing, to a display terminal of the one user, first screen information indicating a setting screen, on which the one user is allowed to set whether log information of the new electrical device is transmitted to a computer of the extracted service provider.

In the aforementioned aspect, when a new electrical device is added to the information providing system, the service provider which intends to acquire log information of the new electrical device is automatically extracted. Then, a display screen, on which the user is allowed to set whether log information of the new electrical device is to be provided to the computer of the extracted service provider, is provided to the display terminal of the user.

According to the aforementioned configuration, each time a new electrical device is added, the user is allowed to set the service provider to which log information of the new electrical device is provided. This makes it possible to prevent providing log information of a new electrical device to a service provider which is not expected to the user, without relying on the user's judgment. Further, each time a new electrical device is added, a service provider associated with the new electrical device is selected. This makes it possible to reduce the user's burden in setting. Further, each time a new electrical device is added, the user is asked to judge whether log information is to be provided. This makes it possible to prevent a case in which it is impossible to discriminate between home appliances registered whether log information is to be provided and home appliances unregistered whether log information is to be provided due to an increase in the number of registered electrical devices, and in which setting as to whether providing log information is erroneously registered.

Further, in the aforementioned aspect, preferably, it may be judged whether a same electrical device as the new electrical device included in the updated second device information is included in the electrical devices indicated by the first device information, and when it is judged that the same electrical device as the new electrical device is included in the electrical devices indicated by the first device information, the service provider associated with the first device information may be extracted.

According to the aforementioned configuration, it is judged whether the same electrical device as the new electrical device included in the updated second device information is included in the electrical devices indicated by the first device information. When it is judged that the same electrical device as the new electrical device is included in the electrical devices indicated by the first device information, a service provider associated with the first device information is extracted.

This makes it possible to specify the service provider which intends to acquire log information of a new electrical device.

Further, in the aforementioned aspect, preferably, when the first database is updated by addition of a new service provider, and when an electrical device to be designated by the new service provider is included in the electrical devices indicated by the second device information, a user associated with the second device information may be extracted from the one or more users, and second screen information indicating a setting screen, on which the associated user is allowed to set whether log information of the electrical device to be designated by the new service provider is transmitted to a computer of the new service provider, may be provided to a display terminal of the associated user.

According to the aforementioned configuration, when a computer of a new service provider is added to the information providing system, a display screen, on which the user is allowed to set whether log information is provided to the new service provider with respect to an electrical device of which acquisition of log information is intended by the new service provider, is provided to the display terminal of the user.

In the aforementioned configuration, each time a new service provider is added, the user is allowed to set whether log information of an electrical device is to be provided to the new service provider. This makes it possible to prevent providing log information of an electrical device to a new service provider which is not expected to the user, without relying on the user's judgment. Further, each time a new service provider is added, an electrical device associated with the new service provider is selected. This makes it possible to reduce the user's burden in setting. Further, each time a new service provider is added, the user is allowed to judge whether log information is to be provided. This makes it possible to prevent a case in which it is impossible to discriminate between home appliances registered whether log information is to be provided and home appliances unregistered whether log information is to be provided due to an increase in the number of registered electrical devices, and in which setting as to whether providing log information is erroneously registered.

Further, in the aforementioned aspect, preferably, the first screen information may include information indicating the number of users who permit transmitting log information of a same electrical device as the new electrical device to the computer of the same service provider as the extracted service provider.

According to the aforementioned configuration, it is possible to display information indicating the number of users who permit transmitting log information of the same electrical device as the new electrical device to the computer of the same service provider as the extracted service provider. This makes it possible to determine whether transmitting log information is permitted by checking the number of the other users who permit transmitting log information. Further, the user can use the number of the other users who permit transmitting log information, as information in determining whether transmitting log information is to be permitted.

Further, in the aforementioned aspect, preferably, when the number of users who permit transmitting the log information to a computer of a specific one of the one or more service providers has reached a predetermined number among the one or more users, third screen information indicating a setting screen, on which a non-permitting user who does not permit transmitting the log information of the electrical device to the computer of the specific service provider among the one or more users is allowed to set whether the log information of the electrical device is transmitted to the computer of the specific service provider, is provided to a display terminal of the non-permitting user.

According to the aforementioned configuration, it is possible to provide a setting screen, on which the user is allowed to set whether log information of an electrical device is transmitted to the computer of the specific service provider, to the display terminal of a non-permitting user who does not permit transmitting log information of an electrical device to the computer of the specific service provider when the number of users who permit transmitting log information to the computer of the specific service provider has reached a predetermined number. This is advantageous in prompting the user to transmit log information.

Further, in the aforementioned aspect, preferably, the third screen information may include information indicating that the number of users who permit transmitting the log information to the computer of the specific service provider has reached the predetermined number.

According to the aforementioned configuration, the user can determine whether the user permits transmitting log information by checking the information indicating that the number of users who permit transmitting log information to the computer of the specific service provider has reached the predetermined number.

Further, in the aforementioned aspect, preferably, the first screen information may indicate a setting screen, on which the one user is allowed to set whether log information of the new electrical device is transmitted to the computer of the extracted service provider with respect to each of types of the log information.

According to the aforementioned configuration, it is possible to set whether log information is to be transmitted to the computer of the service provider with respect to each of the types of log information. This is advantageous in finely setting whether log information is to be provided to a service provider.

Further, in the aforementioned aspect, preferably, the first screen information may include a setting screen, on which the one user is allowed to set a time period during which the log information of the new electrical device is transmitted to the computer of the extracted service provider.

According to the aforementioned configuration, it is possible to set the time period during which log information is provided to the service provider. This makes it possible to provide log information to the service provider only during the time period intended by the user.

An information provision method according to another aspect of the invention is an information provision method for use in an information providing system configured to collect log information from one or more electrical devices of one or more users via a first network, and to transmit the log information to a computer of one or more service providers via a second network. The information provision method includes accumulating, in a first database, a first identifier identifying each of the one or more service providers, and first device information indicating an electrical device to be designated by each of the one or more service providers in association with each other; accumulating, in a second database, a second identifier identifying each of the one or more users, and second device information indicating an electrical device to be used by the one or more users in association with each other; extracting a user associated with the second device information from the one or more users when the first database is updated by addition of a new service provider, and when an electrical device to be designated by the new service provider is included in the electrical devices indicated by the second device information; and providing first screen information indicating a setting screen, on which the associated user is allowed to set whether log information of the electrical device to be designated by the new service provider is transmitted to a computer of the new service provider, to a display terminal of the associated user.

This makes it possible to prevent providing log information of an electrical device to a new service provider which is not expected to the user, without relying on the user's judgment. Further, each time a new service provider is added, an electrical device associated with the new service provider is selected. This makes it possible to reduce the user's burden in setting. Further, each time a new service provider is added, the user is asked to judge whether log information is to be provided. This makes it possible to prevent a case in which it is impossible to discriminate between home appliances registered whether log information is to be provided and home appliances unregistered whether log information is to be provided due to an increase in the number of registered electrical devices, and in which setting as to whether providing log information is erroneously registered.

(Overview of Services to be Provided)

FIG. 1A is a diagram illustrating an overview of services to be provided by the information providing system in the embodiment. The information providing system is provided with a group 1000, a datacenter operating company 1100, and a service provider 1200.

The group 1000 is, for instance, a company, a party, or a home. The scale of the group 1000 does not matter. The group 1000 is provided with a number of devices 101 including a device A and a device B, and a home gateway 1020. The devices 1010 include devices (e.g. a smartphone, a personal computer (PC) or a TV receiver) connectable to the Internet, and devices (e.g. an illumination device, a washing machine, or a refrigerator) incapable of being connected to the Internet by themselves. The devices 1010 may include devices which are not connectable to the Internet by themselves, but are connectable to the Internet via the home gateway 1020. Further, users 1 use the devices 1010 within the group 1000.

The datacenter operating company 1100 is provided with a cloud server 1110. The cloud server 1110 is a virtual server connectable to a variety of devices via the Internet. The cloud server 1110 mainly manages big data, which is difficult to be handled by an ordinary database management tool or a like tool. The datacenter operating company 1100 manages data, manages the cloud server 1110, and operates a datacenter which performs these services. The details of the services to be provided by the datacenter operating company 1100 will be described later.

The datacenter operating company 1100 is not limited to a company which manages data or operates the cloud server 1110. For instance, as illustrated in FIG. 1B, in the case where a device manufacturer which develops and manufactures one of the devices 1010 manages data or manages the cloud server 111, the device manufacturer corresponds to the datacenter operating company 1100. Further, the number of datacenter operating companies 1100 is not limited to one. For instance, as illustrated in FIG. 1C, when a device manufacturer and another managing company jointly or sharingly manage data or operates the cloud server 1110, both or one of the device manufacturer and the managing company corresponds to the datacenter operating company 1100.

The service provider 1200 is provided with a server 1210. The scale of the server 1210 does not matter. For instance, the server 1210 includes a memory in a PC for personal use. Further, the service provider 1200 may not be provided with the server 1210.

In the aforementioned services, the home gateway 1020 is not an essential element. For instance, when the cloud server 1110 manages all the data, the home gateway 1020 is not necessary. Further, when all the devices in a home are connected to the Internet, a device incapable of being connected to the Internet by itself may not exist.

Next, a flow of information in the services is described.

The device A or the device B in the group 1000 individually transmits log information thereof to the cloud server 1110 in the datacenter operating company 1100. The cloud server 1110 accumulates the log information of the device A or of the device B (see the arrow 131 in FIG. 1A). The log information is information indicating e.g. operation conditions or operation dates and times of the devices 1010. For instance, the log information includes a viewing history of TV, video recording reservation information in a recorder, a date and time when a washing machine is operated, a quantity of laundry, a date and time when a refrigerator is opened and closed, or the number of times of opening and closing a refrigerator. The log information is not limited to these information, and may include a variety of types of information acquirable from a variety of types of devices. The log information may be directly provided from the devices 1010 themselves to the cloud server 1110 via the Internet. Further, the log information may be temporarily accumulated in the home gateway 1020 from the devices 1010, and may be provided from the home gateway 1020 to the cloud server 1110.

Next, the cloud server 1110 in the datacenter operating company 1100 provides the accumulated log information to the service provider 1200 unit by unit. The unit may be the amount of information, by which the datacenter operating company 1100 can organize and provide the accumulated information to the service provider 1200, or may be the amount of information required from the service provider 1200. In the embodiment, information is provided unit by unit. Alternatively, information may not be provided unit by unit, and the amount of information to be provided may vary depending on a condition. The log information is stored in the server 1210 owned by the service provider 1200, as necessary (see the arrow 132 in FIG. 1A).

The service provider 1200 organizes the log information into information appropriate for the service to be provided to the user, and provides the organized information to the user. The user to whom information is provided may be a user 1 who uses the devices 1010, or may be a user 2 on the outside. The information provision method to the users 1 and 2 may be such that information is directly provided to the users 1 and 2 from the service provider 1200 (see the arrows 133 and 134 in FIG. 1A). Further, the information provision method to the user 1 may be such that information is provided to the user 1 via the cloud server 1110 in the datacenter operating company 1100 (see the arrows 135 and 136 in FIG. 1A). Further, the cloud server 1110 in the datacenter operating company 1100 may organize the log information into information appropriate for the service to be provided to the user, and may provide the organized information to the service provider 1200.

The user 1 may be identical to or different from the user 2.

In the following, the information providing system in the embodiment of the invention is described referring to the drawings.

The embodiment described in the following section is a preferred exemplary embodiment. In other words, the numerical values, the shapes, the materials, the constituent elements, the disposition of the constituent elements, the connecting manners of the constituent elements, the steps, and the order of the steps are merely an example of the invention, and do not limit the gist of the invention. The invention is specified on the basis of the claims as defined herein. Therefore, although the constituent elements that are not described in the independent claims defining the broadest scope of the invention among the constituent elements in the embodiment may not be necessarily required in order to solve the problems of the invention, they are described as the constituent elements constituting a preferred embodiment.

1. Configuration of Information Providing System

In this section, the information providing system in the embodiment of the invention is described referring to the drawings.

1.1 Overall Configuration of Information Providing System 10

FIG. 2 is a diagram illustrating the overall configuration of an information providing system 10 in the embodiment of the invention. The information providing system 10 is provided with a manufacturer server 100, a first service provider server 200 a, a second service provider server 200 b, a third service provider server 200 c, home appliances 300, and a user terminal 400.

The home appliances 300 are e.g. a TV receiver, a body composition meter, or an activity meter. The home appliances 300 are home appliances of which home appliance history information is collected by the information providing system 10.

The home appliances 300 may be e.g. an air conditioner, AV equipment such as a TV receiver, a washing machine, an illumination device, an electronic shutter, or an interphone. Further, the home appliances 300 may be any electrical devices to be used in a home including housing equipment, sensors for measuring and detecting the dwelling environment, and electrical vehicles. The home appliances 300 may be any electrical devices as far as the devices are capable of collecting log information.

The user terminal 400 is e.g. a personal computer, a mobile phone, or a mobile terminal such as a tablet terminal or a smartphone.

The manufacturer server 100 is communicatively connected to the home appliances 300 via a first network 501. Further, the manufacturer server 100 is communicatively connected to each of the first service provider server 200 a, the second service provider server 200 b, and the third service provider server 200 c via a second network 502. Further, the manufacturer server 100 is communicatively connected to the user terminal 400 via a third network 503. The first network 501, the second network 502, and the third network 503 may all be the same, or may all be different from each other. Further alternatively, at least two of the first network 501, the second network 502, and the third network 503 may be the same.

The first network 501, the second network 502, and the third network 503 may be constituted by e.g. the Internet, a mobile phone communication network, or an LAN (Local Area Network).

The information providing system 10 collects log information from one or more home appliances 300 of one or more users via the first network 501, and transmits the log information to a computer (the first service provider server 200 a, the second service provider server 200 b, or the third service provider server 200 c) of one or more service providers via the second network 502.

In the embodiment, the first service provider server 200 a, the second service provider server 200 b, and the third service provider server 200 c may also be generically called as a service provider server 200.

1.2 Configuration of Manufacturer Server 100

FIG. 3 is a diagram illustrating a configuration of the manufacturer server 100 in the embodiment of the invention. The manufacturer server 100 is provided with a control unit 101, a history information DB (database) 102, a certificate generation unit 103, a certificate verification unit 104, and a communication unit 105.

The control unit 101 controls the history information DB 102 with use of an access control list, and manages user information or home appliance history information. The access control list will be described later. In response to receiving a request to provide home appliance history information from a service provider server, the control unit 101 transmits, to the certificate verification unit 104, a request to verify a public key certificate (not illustrated) of a service provider received from the service provider server. In response to receiving a notification that verification was successful from the certificate verification unit 104, the control unit 101 judges whether home appliance history information is to be provided to the service provider server. When it is judged that home appliance history information is to be provided, the control unit 101 judges which one of the home appliance history information is to be provided to the service provider server. The control unit 101 requests the certificate generation unit 103 to issue a home appliance history access certificate. In response to receiving the home appliance history access certificate issued by the certificate generation unit 103, the control unit 101 transmits the home appliance history access certificate to the service provider server via the communication unit 105. An information provision method for providing home appliance history information from the history information DB 102 with use of an access control list will be described later.

The history information DB 102 stores user IDs for identifying the users and home appliance history information.

The home appliance history information is information indicating an operation history of home appliances 300 by the user (e.g. a history of operating the TV channels), and a user information history to be measured or detected by use of the home appliances 300 by the user (e.g. a history of the user's body weight to be measured with use of a body composition meter by the user).

FIG. 4 is a diagram illustrating an example of data to be stored in the history information DB in the embodiment of the invention. The history information DB 102 stores home appliance types indicating the types of home appliances 300 owned by the user to be identified by the user ID, and home appliance history information of the home appliances 300 represented by the home appliance types in association with each other, with respect to each of the user IDs. In the embodiment, the home appliance types are the names of the home appliances. Alternatively, the home appliance types may be serial numbers or model numbers of the home appliances, or may be combinations of serial numbers and model numbers.

FIG. 4 illustrates that the user whose user ID is “ID11” registers a body composition meter and a TV receiver as home appliances in the information providing system 10, and that home appliance history information of each of the home appliances is stored in the history information DB 102. Further, the history information DB 102 stores, as home appliance history information of the body composition meter, information describing “2012.1.1, BODY WEIGHT: 55 KG, BODY FAT PERCENTAGE: 18%”, and “2012.1.3, BODY WEIGHT: 56 KG, BODY FAT PERCENTAGE: 19%”. This means that when the user measured her body composition on Jan. 1, 2012, the body weight was 55 kg, and the body fat percentage was 18%; and when the user measured her body composition on Jan. 3, 2012, the body weight was 56 kg, and the body fat percentage was 19%. Likewise, the history information DB 102 stores, as home appliance history information of the TV receiver, a viewing history of TV programs which the user watched on TV i.e. “2012.1.1, 18:00 DRAMA, 20:00 NEWS” and “2012.1.3, 10:00 ANIMATION, 13:00 DRAMA”.

Further, the user whose user ID is “ID12” registers a body composition meter as a home appliance in the information providing system 10. The history information DB 102 stores home appliance history information “2011.12.30, BODY WEIGHT: 80 KG, BODY FAT PERCENTAGE: 22%” and “2012.1.3, BODY WEIGHT: 82 KG, BODY FAT PERCENTAGE: 22%”.

These home appliance history information is information to be periodically or non-periodically uploaded from the home appliances that are registered in advance in the information providing system 10 by the users to the manufacturer server 100. The home appliance history information is an example of log information.

In response to receiving a request to issue a home appliance history access certificate from the control unit 101, the certificate generation unit 103 generates a home appliance history access certificate.

FIG. 5 is a diagram illustrating an example of a home appliance history access certificate in the embodiment of the invention. The home appliance history access certificate is a certificate such that a home appliance manufacturer electronically signs with use of a signature generation key (not illustrated) of the home appliance manufacturer with respect to a service provider ID and with respect to a service provider public key. The service provider ID is an identifier for identifying the service provider server. The service provider public key is a public key to be issued by the service provider server. The service provider server can acquire home appliance history information accessible by the service provider server by presenting the home appliance history access certificate to the manufacturer server. Further, the certificate generation unit 103 may include the type of a home appliance to be provided to the service provider server or information to be provided in the home appliance history access certificate.

In response to receiving a public key certificate issued by the service provider server from the control unit 101, the certificate verification unit 104 verifies the received public key certificate. Further, in response to receiving a home appliance history access certificate issued by the service provider server from the control unit 101, the certificate verification unit 104 verifies the received home appliance history access certificate with use of a signature verification key (not illustrated) of the home appliance manufacturer.

The communication unit 105 stores certificates necessary for SSL communication.

1.2.1 Method for Providing Home Appliance History with use of Access Control List

FIG. 6 is a diagram illustrating an example of the access control list in the embodiment of the invention. The access control list indicates user information providing acceptance/non-acceptance such that from which one of the home appliances, home appliance history information is acquired, and of which one of the user IDs, providing home appliance history information is permitted for each of the home appliances with respect to each of the service provider IDs. In the access control list, the service provider ID for identifying the service provider, the type of a home appliance of which home appliance history information is providable to the service provider, and the user ID of the user who does not provide home appliance history information to the service provider are associated with each other. In FIG. 6, regarding the fitness service A whose service provider ID is “SID_a”, it is possible to acquire home appliance history information from the body composition meter, the TV receiver, and the blood pressure meter, and there is no user who sets such that home appliance history information of the body composition meter is not provided. In FIG. 6, none of the users sets whether home appliance history information of the body composition meter is provided to the service provider A.

For instance, when the user whose user ID is “ID11” does not provide home appliance history information of the body composition meter to the fitness service A, the user ID “ID11” is recorded in the column of un-providable user ID in the access control list. This means that home appliance history information of the body composition meter of the user whose user ID is “ID11” is not provided.

The control unit 101 accumulates, in the access control list (first database), the service provider ID (first identifier) identifying each of one or more service providers, and a home appliance type (first device information) indicating a home appliance to be designated by each of the one or more service providers in association with each other.

The control unit 101 accumulates, in the history information DB 102 (second database), the user ID (second identifier) identifying each of one or more users, and a home appliance type (second device information) indicating a home appliance to be used by the one or more users in association with each other.

When the second device information is updated by addition of a new home appliance to be used by one of the one or more users, and the new home appliance is included in the home appliances indicated by the first device information, the control unit 101 extracts a service provider associated with the first device information. Then, the control unit 101 provides, to the user terminal 400 (display terminal) of the one user, first screen information indicating a setting screen, on which the user is allowed to set whether log information of the new home appliance is to be transmitted to the computer of the extracted service provider.

Further, the control unit 101 judges whether the same electrical device as the new electrical device included in the updated second device information is included in the electrical devices indicated by the first device information. When it is judged that the same electrical device as the new electrical device is included in the electrical devices indicated by the first device information, the control unit 101 extracts a service provider associated with the first device information.

Further, when the first database is updated by addition of a new service provider, and a home appliance to be designated by the new service provider is included in the home appliances indicated by the second device information, the control unit 101 extracts a user associated with the second device information from the one or more users. Then, the control unit 101 provides, to the user terminal 400 (display terminal) of the associated user, second screen information indicating a setting screen, on which the user is allowed to set whether log information of the home appliance to be designated by the new service provider is transmitted to the computer of the new service provider.

Subsequently, the communication unit 406 transmits the home appliance ID input through the input unit 404 to the manufacturer server 100 (Step S51). The communication unit 406 transmits the user ID together with the home appliance ID. The communication unit 105 of the manufacturer server 100 receives the home appliance ID transmitted by the user terminal 400.

FIG. 13 is a diagram illustrating an example of a home appliance registration screen to be displayed when the home appliance registration process is performed in the embodiment of the invention. The home appliance ID is an ID for identifying the home appliance. The home appliance ID may be printed on a housing of a home appliance or on a printed matter to be enclosed together with a home appliance. In this case, the user inputs the printed home appliance ID with use of the input unit 404. Further, the user terminal 400 may acquire the home appliance ID from the home appliance 300. For instance, the user terminal 400 may communicate with the home appliance 300, acquire the home appliance ID from the home appliance 300, and transmit the acquired home appliance ID to the manufacturer server 100.

Subsequently, the control unit 101 of the manufacturer server 100 specifies the home appliance type from the home appliance ID received from the user terminal 400, and registers the specified home appliance type in the history information DB 102 in association with the user ID (Step S52). In the history information DB 102 illustrated in FIG. 4, the user whose user ID is “ID13” registers a body composition meter as the home appliance in the information providing system 10. The control unit 101 stores in advance a table in which home appliance IDs and home appliance types are associated with each other. The control unit 101 specifies the home appliance type from the home appliance ID by referring to the table.

Subsequently, the control unit 101 of the manufacturer server 100 extracts a service provider ID associated with the newly registered home appliance type from the access control list (Step S53).

Subsequently, the control unit 101 generates a provision confirmation screen for use in asking the user whether home appliance history information is to be provided to the service provider server which is associated with the extracted service provider ID (Step S54).

Subsequently, the communication unit 105 transmits the provision confirmation screen generated by the control unit 101 to the user terminal 400 (Step S55). The communication unit 406 of the user terminal 400 receives the provision confirmation screen transmitted by the manufacturer server 100.

Subsequently, the communication unit 406 transmits, to the manufacturer server 100, an input result indicating whether the home appliance history information input through the input unit 404 is provided to the service provider server (Step S58). The communication unit 105 of the manufacturer server 100 receives the input result transmitted by the user terminal 400.

FIG. 14 is a diagram illustrating an example of a provision confirmation screen for use in asking the user whether home appliance history information of the registered home appliance 300 is to be provided to the service provider server. Setting as to whether home appliance history information is provided to the service provider server is described using the example of FIG. 14.

The control unit 101 of the manufacturer server 100 retrieves a service provider ID by which home appliance history information of a body composition meter registered in the access control list is provided when the body composition meter is registered by the user terminal 400. In the example of FIG. 6, the service provider which provides home appliance history information of a body composition meter is the service provider (fitness service A) whose service provider ID is “SID_a”, and the service provider (diet service B) whose service provider ID is “SID_b”.

As illustrated in FIG. 14, the control unit 101 of the manufacturer server 100 generates a provision confirmation screen including a service provider associated with an extracted service provider ID, a home appliance registered by the user, home appliance history information to be provided from the registered home appliance to the service provider, and checkboxes with which the user is allowed to select whether home appliance history information is to be provided. The control unit 101 displays the generated provision confirmation screen on the user terminal 400. The user is allowed to select whether home appliance history information is to be provided with respect to each of the service providers, and to input the selection result through the input unit 404. The input result is transmitted from the user terminal 400 to the manufacturer server 100.

Subsequently, the control unit 101 of the manufacturer server 100 registers the user ID of the user who does not provide home appliance history information in the access control list on the basis of an input result as to whether home appliance history information selected by the user is provided to the service provider (Step S59). When the home appliance history information is not provided to the service provider, the control unit 101 registers the user ID in the access control list. On the other hand, when the home appliance history information is provided to the service provider, the control unit 101 does not register the user ID in the access control list. As described above, the control unit 101 can discriminate whether user's home appliance history information is to be provided by managing the user ID of the user who does not provide home appliance history information by the access control list.

FIG. 15 is a diagram illustrating an example of an access control list, which is set such that home appliance history information of a body composition meter is not provided by the user. In Step S57, when the user whose user ID is “ID13” does not provide home appliance history information of a body composition meter to the fitness service A, and provides the home appliance history information of the body composition meter to the diet service B, the access control list is set such that “ID13” is registered as the unprovidable user ID associated with the body composition meter identified by “SID_a”, and that “ID13” is not registered as the unprovidable user ID associated with the body composition meter identified by “SID_b”.

In the embodiment, the access control list is configured such that the user ID of the user who does not provide home appliance history information is stored in association with the home appliance type. The invention is not specifically limited to the above. The user ID of the user who provides home appliance history information may be stored in association with the home appliance type.

When it is judged that verification of the home appliance history access certificate has failed (NO in Step S84), the process is terminated.

On the other hand, when it is judged that verification of the home appliance history access certificate was successful (YES in Step S84), the communication unit 105 notifies the first service provider server 200 a that verification of the home appliance history access certificate was successful (Step S85). The communication unit 205 of the first service provider server 200 a receives a notification that verification of the home appliance history access certificate transmitted by the manufacturer server 100 was successful.

Subsequently, the control unit 201 of the first service provider server 200 a selects home appliance history information to be acquired, and transmits, to the manufacturer server 100, a home appliance history information acquisition request indicating a request to acquire the selected home appliance history information (Step S86). The communication unit 105 of the manufacturer server 100 receives the home appliance history information acquisition request transmitted by the first service provider server 200 a.

Subsequently, the control unit 101 of the manufacturer server 100 specifies the home appliance history information to be provided to the first service provider server 200 a, referring to the access control list, and acquires the specified home appliance history information from the history information DB 102 (Step S87).

When the aforementioned operation is performed, the control unit 101 selects the home appliance history information to be provided to the first service provider server 200 a as follows, with use of the access control list. The control unit 101 acquires, from the history information DB 102, home appliance history information associated with the home appliance type having the user ID other than the unprovidable user ID, from the home appliance types of which home appliance history information is provided to the first service provider server 200 a.

Subsequently, the communication unit 105 transmits the acquired home appliance history information to the first service provider server 200 a (Step S88). The communication unit 205 of the first service provider server 200 a receives the home appliance history information transmitted by the manufacturer server 100.

Alternatively, the first service provider server 200 a may acquire home appliance history information that is provided from the home appliance after the point of time when it is set such that home appliance history information is provided by the user. Further alternatively, the first service provider server 200 a may acquire not only home appliance history information that is provided after the point of time when it is set such that home appliance history information is provided by the user, but also home appliance history information that is provided before the point of time when it is set such that home appliance history information is provided by the user.

1.5.6 Operation of Second Service Provider Registration Process

FIG. 18 and FIG. 19 are sequence diagrams illustrating an operation of the second service provider registration process in the embodiment of the invention. FIG. 20 is a diagram illustrating an example of an access control list, in which a new service provider is added.

The processes from Step S101 to Step S107 of the second service provider registration process illustrated in FIG. 18 are the same as the processes from Step S11 to Step S17 of the first service provider registration process illustrated in FIG. 10, and therefore, description of the processes from Step S101 to Step S107 is omitted herein.

The control unit 101 of the manufacturer server 100 extracts a home appliance type associated with a newly registered service provider ID from the access control list (Step S108).

Subsequently, the control unit 101 retrieves the user ID having the extracted home appliance type from the history information DB, and judges whether there is the user ID having the extracted home appliance type (Step S109).

In the access control list illustrated in FIG. 20, a service provider (insurance service C) whose service provider ID is “SID_c” is newly registered, and the newly registered service provider is associated with a body composition meter and with a blood pressure meter as the home appliance types of which home appliance history information is acquired. In this case, the control unit 101 extracts, from the access control list, a body composition meter and a blood pressure meter associated with the newly registered service provider ID (SID_c). Then, the control unit 101 retrieves the user ID associated with the extracted body composition meter and the extracted blood pressure meter from the history information DB 102, and judges whether there is the user ID associated with the extracted body composition meter and the extracted blood pressure meter.

When it is judged that there is no user ID having the extracted home appliance type (NO in Step S109), the process is terminated.

On the other hand, when it is judged that there is the user ID having the extracted home appliance type (YES in Step S109), the control unit 101 generates a provision confirmation screen for use in asking the user whether home appliance history information is to be provided to the service provider server associated with the newly registered service provider ID (Step S110). The control unit 101 asks the user whether home appliance history information is to be provided to the service provider, using the provision confirmation screen.

The communication unit 406 of the user terminal 400 receives the provision confirmation screen transmitted by the manufacturer server 100. Alternatively, the provision confirmation screen transmission method may be notified by an electronic mail, or may be notified when the application of the information providing system is activated on the user terminal 400.

Subsequently, the display unit 405 of the user terminal 400 displays the received provision confirmation screen (Step S112).

Subsequently, the input unit 404 accepts user's input as to whether home appliance history information is provided to the service provider server (Step S113).

Subsequently, the communication unit 406 transmits, to the manufacturer server 100, an input result as to whether home appliance history information input by the input unit 404 is provided to the service provider server (Step S114). The communication unit 105 of the manufacturer server 100 receives the input result transmitted by the user terminal 400.

FIG. 21 is a diagram illustrating an example of a provision confirmation screen for use in asking the user whether home appliance history information of an already registered home appliance 300 is to be provided to a newly registered service provider server. On the provision confirmation screen illustrated in FIG. 21, the user who registers a body composition meter and a blood pressure meter in the information providing system 10 is asked whether home appliance history information is to be provided.

As illustrated in FIG. 21, the control unit 101 generates a provision confirmation screen including a newly registered service provider, a home appliance which is already registered, and whose home appliance history information is providable to the newly registered service provider, home appliance history information to be provided from the home appliance to the service provider, and checkboxes with which the user is allowed to select whether home appliance history information is to be provided. The control unit 101 displays the generated provision confirmation screen on the user terminal 400. The user is allowed to select whether home appliance history information is to be provided with respect to each of the home appliances, and to input the selection result through the input unit 404. The input result is transmitted from the user terminal 400 to the manufacturer server 100.

Subsequently, the control unit 101 of the manufacturer server 100 registers the user ID of the user who does not provide home appliance history information in the access control list on the basis of an input result as to whether home appliance history information selected by the user is provided to a service provider (Step S115). When home appliance history information is not provided to a service provider, the control unit 101 registers the user ID in the access control list. On the other hand, when home appliance history information is provided to a service provider, the control unit 101 does not register the user ID in the access control list. As described above, the control unit 101 can discriminate whether user's home appliance history information is to be provided by managing the user ID of the user who does not provide home appliance history information by the access control list.

FIG. 22 is a diagram illustrating an example of an access control list, in which setting as to whether home appliance history information is provided with respect to a newly registered server provider ID is made. The access control list illustrated in FIG. 22 is an example, in which the user whose user ID is “ID 14” has selected that home appliance history information of both of a body composition meter and a blood pressure meter is not provided to the newly registered service i.e. the insurance service C. In this case, in the access control list, “ID14” is registered as the unprovidable user ID associated with the body composition meter and with the blood pressure meter having the newly registered service provider ID “SID_c”.

1.6 Modifications of Provision Confirmation Screen

Next, modifications of the provision confirmation screen in the embodiment are described.

1.6.1 First Modification of Provision Confirmation Screen

The control unit 101 may generate a provision confirmation screen on which one user is allowed set whether log information of a new home appliance is transmitted to the computer of an extracted service provider with respect to each of the types of log information.

FIG. 23 is a diagram illustrating a first modification of the provision confirmation screen. As illustrated in FIG. 23, the provision confirmation screen may not accept setting as to whether home appliance history information is provided with respect to each of the home appliances, but may accept setting as to whether home appliance history information is provided with respect to each of the types of home appliance history information.

For instance, when a newly installed home appliance is a body composition meter, it is possible to set whether each of the measurement date, the body weight, and the body fat percentage is to be provided to the service provider of the fitness service A. Further, it is also possible to set whether each of the measurement date, the body weight, and the body fat percentage is to be provided to the service provider of the diet service B.

In this way, it is possible to set whether log information is to be transmitted to the computer of a service provider with respect to each of the types of log information. This is advantageous in finely setting whether log information is to be provided to a service provider.

1.6.2 Second Modification of Provision Confirmation Screen

The provision confirmation screen may include information indicating the number of users who permit transmitting log information of the same home appliance as the new home appliance to the computer of the same service provider as the extracted service provider.

FIG. 24 is a diagram illustrating a second modification of the provision confirmation screen. As illustrated in FIG. 24, the provision confirmation screen may include the number of the other users who provide home appliance history information to a service provider.

In the aforementioned case, the control unit 101 counts the number of user IDs which are associated with the same home appliance type as the type of the newly registered home appliance, referring to the history information DB 102, and counts the number of unprovidable user IDs having a home appliance associated with the service provider ID of the same service provider as the extracted service provider, referring to the access control list. Then, the control unit 101 calculates the number of the other users who provide home appliance history information to the service provider by subtracting the number of unprovidable user IDs from the number of user IDs associated with the same home appliance type as the type of the newly registered home appliance.

The control unit 101 adds the calculated number of the other users who provide home appliance history information to the service provider on the provision confirmation screen.

In this way, it is possible to display information indicating the number of users who permit transmitting log information of the same home appliance as a new home appliance to the computer of the same service provider as the extracted service provider. This allows for the user to determine whether the user permits transmitting log information by checking the number of the other users who permit transmitting log information. Further, the user can use the number of the other users who permit transmitting log information, as information in determining whether the user permits transmitting log information.

1.6.3 Third Modification of Provision Confirmation Screen

The provision confirmation screen may include a setting screen on which one user is allowed to set a time period during which log information of a new home appliance is transmitted to the computer of an extracted service provider.

FIG. 25 is a diagram illustrating a third modification of the provision confirmation screen. As illustrated in FIG. 25, the provision confirmation screen includes a time period during which home appliance history information is provided to a service provider. Specifically, the user is allowed to set not only whether home appliance history information is to be provided to a service provider but also a time period during which home appliance history information is provided to a service provider.

For instance, on the provision confirmation screen illustrated in FIG. 25, when home appliance history information is provided to the fitness service A, setting as to the time period during which home appliance history information is provided is accepted. Then, the user inputs an intended time period during which home appliance history information is provided.

The control unit 101 may transmit, to the user terminal 400, a provision confirmation screen upon lapse of a time period, which is set by the user and during which home appliance history information is provided to the service provider.

In this way, it is possible to set a time period during which log information is provided to a service provider. This makes it possible to provide log information to a service provider during a time period intended by the user.

1.6.4 Fourth Modification of Provision Confirmation Screen

When the number of users who permit transmitting log information to the computer of a specific one of one or more service providers has reached a predetermined number among one or more users, the control unit 101 may provide, to the user terminal 400 (display terminal) of a non-permitting user, a provision confirmation screen on which the non-permitting user who does not permit transmitting log information of a home appliance to the computer of the specific service provider is allowed to set whether log information of the home appliance is transmitted to the computer of the specific service provider, among the one or more users.

Further, the provision confirmation screen may include information indicating that the number of users who permit transmitting log information to the computer of a specific service provider has reached a predetermined number.

FIG. 26 is a diagram illustrating a fourth modification of the provision confirmation screen. As illustrated in FIG. 26, the provision confirmation screen may include the number of users who provide home appliance history information to a service provider.

For instance, when the number of users who provide home appliance history information to a predetermined service provider has reached a predetermined number (e.g. one thousand), the control unit 101 extracts the user ID determined as an unprovidable user ID with respect to the home appliance type associated with the predetermined service provider, referring to the access control list. Then, the control unit 101 provides a provision confirmation screen to the user terminal 400 of the non-permitting user identified by the extracted user ID. When the aforementioned operation is performed, the number of users who permit transmitting log information to the predetermined service provider is displayed on the provision confirmation screen.

In this way, it is possible to provide a provision confirmation screen to the user terminal 400 of a non-permitting user who does not permit transmitting log information of a home appliance to the computer of a specific service provider when the number of users who permit transmitting log information to the computer of the specific service provider has reached a predetermined number. This is advantageous in prompting the user to transmit log information.

Further, the user is allowed to determine whether the user permits transmitting log information by checking the information indicating that the number of users who permit transmitting log information to the computer of a specific service provider has reached a predetermined number.

1.7 Advantageous Effects of Embodiment

The device manufacturer safely and integrally manages various types of user information including history information relating to use of home appliances by the users, and only the permitted information is provided to each of the service providers on the basis of an access control list. The access control list is a list to be managed whether the user provides home appliance history information of a home appliance with respect to each of the service providers. The service provider server can acquire home appliance history information permitted to the service provider server by transmitting a certificate issued by the manufacturer server.

In the aforementioned aspect, when a new home appliance is added to the information providing system, the service provider which intends to acquire log information of the new home appliance is automatically extracted. Then, a display screen, on which the user is allowed to set whether log information of the new home appliance is to be provided to the computer of the extracted service provider, is provided to the display terminal of the user.

According to the aforementioned configuration, each time a new home appliance is added, the user is allowed to set the service provider to which log information of the new home appliance is provided. This makes it possible to prevent providing log information of a new home appliance to a service provider which is not expected to the user, without relying on the user's judgment. Further, each time a new home appliance is added, a service provider associated with the new home appliance is selected. This makes it possible to reduce the user's burden in setting. Further, each time a new home appliance is added, the user is asked to judge whether log information is to be provided. This makes it possible to prevent a case in which it is impossible to discriminate between home appliances registered whether log information is to be provided and home appliances unregistered whether log information is to be provided due to an increase in the number of registered home appliances, and in which setting as to whether providing log information is erroneously registered.

Further, in the aforementioned aspect, when a computer of a new service provider is added to the information providing system, a display screen, on which the user is allowed to set whether log information is to be provided to the new service provider with respect to a home appliance of which acquisition of log information is intended by the new service provider, is provided to the display terminal of the user.

According to the aforementioned configuration, each time a new service provider is added, the user is allowed to set whether log information of a home appliance is to be provided to the new service provider. This makes it possible to prevent providing log information of a home appliance to a new service provider which is not expected to the user, without relying on the user's judgment. Further, each time a new service provider is added, a home appliance associated with the new service provider is selected. This makes it possible to reduce the user's burden in setting. Further, each time a new service provider is added, the user is allowed to judge whether log information is to be provided. This makes it possible to prevent a case in which it is impossible to discriminate between home appliances registered whether log information is to be provided and home appliances unregistered whether log information is to be provided due to an increase in the number of registered home appliances, and in which setting as to whether providing log information is erroneously registered.
